SAFETY PRECAUTIONS
DO NOT operate blower until the operator completely comprehends the contents of this manual.
The blower is a specialized type of powered equipment, designed for a specific job function and requires adequate and
thorough instruction BEFORE it is operated. Each person must receive adequate professional instruction regarding proper
operation. Read and understand this User Manual and the material supplied by the motor manufacturer. Refer to OSHA
2207, for job safety and health rules and regulations (1926 and 1910) covering construction.
DO NOT allow minors to operate the blower. Bystanders, children and animals should not be allowed in the area where a
blower is in use.
DO NOT use an undersized wire size on electrical power cable or extension cords if used. This will adversely limit the
starting and load carrying capabilities of the motor. Always use minimum AWG wire sizes for motor branch circuits.
Consult the National Electric Code Tables, Article 400, for specific information.
DO NOT operate the blower without the inlet and outlet screens properly secured and in place. Replace screens with
factory replacements (OEM). The screen grid must comply with current OSHA regulations regarding protective enclosures
to prevent personal injury to the operator(s). Ensure the structural integrity of the screens will allow them to serve their
protective function. Keep both screens free from obstructions and debris to allow maximum airflow.
DO NOT stand directly in front of and/or face the blower outlet. Personal injury may result from debris being thrown from
the blower fan at relatively high velocity.
DO NOT use electrical transformer in an effort to modify or alter the motor frequency (HZ).
DO implement an operational safety program for this blower, to include but not limited to: instructional requirements for
operation, applicable OSHA requirements, local laws and regulations, job site safety and blower maintenance. Operators
must be fully instructed regarding the specifics of this safety program. (Ref. 29CFR 1926.21 (b) (2)).
DO ensure the blower is in its original, factory configuration and has not been modified. Any modifications may result in
potentially dangerous configurations that can lead to property damage and/or personal injury. As well as voiding the
manufacturer’s warranty.
DO ensure operator(s) are in adequate physical condition, mental health and not under the influence of any substance
(drugs, alcohol, etc.) which might impair vision, dexterity or judgment. If you have any condition that might be aggravated
by strenuous work, check with your doctor before operating the blower. Guard against the possibility of back related
injuries. Always use proper lifting techniques when moving or carrying blower.
DO wear sturdy and snug fitting clothing. Never wear loose fitting clothing or anything that could become caught on
controls or moving parts. Wear long pants to protect your legs. To improve your grip and protect your hands, wear heavy
duty, non-slip gloves. DO wear steel-toed safety boots with non-slip soles. Sneakers or other similar type shoes do not
provide adequate protection.
DO wear an approved safety hard hat. Noise, generated by the blower, may damage your hearing. Wear sound barriers
(ear plugs or ear mufflers). Continuous and regular operators should have their hearing checked regularly.
DO a visual inspection of the blower and check for damaged, worn, loose and/or broken parts. Ensure all safety devices
are operable and information decals are readable. Check to see that the blower and all related accessories are in good
mechanical condition before use.

5
DO verify that the blower uses appropriate electrical cord and NEMA plug. Electrically driven blowers (A.C.), are designed
to operate ONLY from a grounded 115 volt AC, 60Hz single-phase power source. All electrical wiring installations and
connections must comply with all applicable NEC statutes and with all applicable local codes and practices. (Consult
current National Electric Code publications for specific information.)
DO ground the blower motor securely. Ensure the “grounding” wire and/or device is properly grounding the motor. Failure
to properly ground the motor may cause an electrical shock and/or electrocution, resulting in personal injury or even death.
DO use a ground fault circuit interrupter (GFCI). A GFCI is a safety device that disconnects power from a circuit to a load
when a potentially dangerous condition occurs. The GFCI acts like a fast-acting fuse or circuit breaker, sensing small
imbalances in the circuit caused by current leakage, and shutting off electricity within 25mS (milliseconds). Use of a
portable GFCI gives on-the-job protection from electrical shock hazards caused by ground faults in commercial, industrial
and residential applications.
(For specific information, consult the NEC publications and OSHA publications 210-22D for construction sites and 555-3 for
marina’s or for use around any area containing water.)
DO know where the controls are, how they operate, and how to stop the blower in an emergency.
DO verify the location classification. Certain job site locations may be classified as hazardous because of explosive
concentrations of gas, vapor or dust in the atmosphere. The National Electric Code divides these locations into Classes
and Groups according to the type of explosive agent. For specific information, consult the NEC, Section 500. Use Allegro
Explosion-Proof Blowers for operation in an explosive or flammable atmosphere. The use of any other blower not designed
for use in a Hazardous Location may result in personal injury or death.
DO place the blower on secure footing to prevent it from shifting while in use. Such movement can cause injury to the
operator(s) or damage to the blower itself.
DO ensure blower is operated in a horizontal position to meet the enclosure definition. The blower is designed for operation
in job site areas that are reasonably dry, clean and provide for a continuous, dynamic source of air for cooling the motor.
Any questions about operating environments, contact the Allegro Technical Support, before using the blower.
WARNINGS AND LIMITATIONS
Manufacturing tolerances and specific operating parameters will affect the overall flow rate(s) for each particular blower.
Actual flow rate will decrease when the total length of the ducting is increased more than 15 feet (7.6m). Actual flow rates
may change if blower is used with ducts manufactured and/or supplied by other sources.
CAUTION!
The final working procedure for any job application involving the use of the blower must be individually
determined after careful analysis of all factors and/or conditions present. The nearest OSHA office is
a valuable source for applicable information regarding the operation of the blower.
ATTENTION !
La procédure de travail final pour toute demande d'emploi impliquant l'utilisation de la soufflerie doit

OPERATION
Use of Duct:
1) Operate the blower upwind from the work location and with the air inlet facing into the relative wind to maximize air flow.
2) The Allegro flexible ducts are for use with Allegro blowers.
a) All are of the retractable, non-collapsible design.
b) Each duct is supplied with a nylon strap to secure each end to the blower and/or a duct connector. To join two
sections of duct, use a duct-to-duct connector (P/N 9500-01 8”, 9550-01 12”, or 9600-01 16”).
c) When using statically conductive ducting, the integrated grounding wire must be properly:
i) Grounded to the blower chassis.
ii) Linked to any additional grounding wire or duct used.

3) If Blower has an attached canister, verify canister and lid are secure before moving or storage. Release ducting lid and
extend ducting before operating motor.
4) Maximum duct lengths will vary for each blower and environment. Generally, increasing lengths will decrease flow
rates.
5) When changing canister configuration, detach the rubber draw latches and release the canister, re-align to opposite side
of the blower. To re-attach, pull canister draw latches over the latch keepers to secure the canister to the blower.
6) For exhaust (air blowing) operations, connect the duct to the blower outlet.
7) For extraction (air evacuation) operations, connect the canister/duct to the blower inlet. Ensure ducting does not collapse
during operation. Allegro ducting is reinforced to prevent the vacuum force generated by the blower’s suction from
collapsing the duct.
Voltage and Power Selection:
1) The voltage, frequency and phase of the power supply must be consistent with the motor nameplate rating.
a) The motor will operate satisfactorily on voltages within 10% of the nameplate value or frequency within 5%. The
combined variation must not exceed 10%.
2) The Allegro AC blowers are designed to operate from a grounded, 115 or 220 VAC single-phase power source.
a) It’s crucial to the performance of the blower the proper power source is selected.
b) Operation from an inadequate power source or use of incorrect electrical plug may result in property damage and/or
personal injury.
3) Select blowers are supplied with a NEMA 5-15, 5-20(EX), 6-20(EX) plugs or 12 VDC clips (excluding 220V/50Hz
blowers).
a) Do not change or alter the plug, as this will affect the performance of the blower.
b) Operation from an inadequate power source or use of incorrect electrical plug may result in property damage and/or
personal injury.
DC models require 12 VDC (Attach red lead to the positive terminal and black lead to the negative terminal battery, e.g. car
battery).
DANGER!
Before using the blower, check all applicable federal, state, industry and local regulations regarding the
use of flame resistant and/or self-extinguishing duct materials for the intended job applications. It is the
responsibility of the owner(s) and/or operator(s) to determine that the duct material in use for the job
application meets all applicable fire code and OSHA requirements.
DANGER!
Avant d'utiliser le ventilateur, vérifiez toutes applicables les règlements fédéraux, d'état, de l'industrie et
locales concernant l'utilisation de résistant à la flamme et / ou matériaux auto-extinguibles conduits pour
